Masseter Botox, also known as masseter muscle Botox or jawline Botox, refers to the injection of botulinum toxin into the masseter muscles, which are the muscles responsible for chewing and clenching the jaw. This procedure is typically done for cosmetic purposes to achieve a slimmer and more contoured appearance of the lower face. By injecting Botox into the masseter muscles, the muscles gradually weaken and reduce in size over time. This can result in a softer, less square jawline, which is desirable for some individuals seeking a more feminine or balanced facial profile. Additionally, Masseter Botox can help alleviate symptoms associated with jaw clenching and teeth grinding, such as jaw pain and headaches. Masseter Botox is a minimally invasive procedure with relatively few side effects, though temporary swelling or bruising at the injection sites may occur. The effects of Masseter Botox typically last for several months before gradually wearing off, necessitating repeat treatments for maintenance.
